PUMPING MECHANISM FOR VACUUM -CLEANERS.

I Specification of Letters Patent.

Patented May 4,1915.

Application filed. May 16, 1914. Serial No. 839,011.

To all whom it may concern Be it known that I, HOWARD Eoxnn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Pumping Mechanism for Vacuum-Cleaners, of which the following is a specification.

My invention relates to vacuum cleaners of the type employing a casing and one or more bellows, together with a dirt receptacle, the'purpose of my invention being to produce a neat and compact vacuum cleaner having a minimum of parts, and all of its parts being readily accessible.

My invention further relatesto improved mechanism for actuating the vacuum bellows by hand, in such manner that practically any relative movement between the handles employed will cause the device to produce a partial vacuum within the casing.

My invention further relates to various improvements in vacuum cleaners, for the purpose of improving the general eiiiciency thereof. I

Reference is. made to the accompanying drawings forming a part of this specification, and in which like letters indicate like parts.

Figure 1 is'a perspective of myimproved vacuum cleaner complete. Fig. 2 is a fragmentary perspective partly broken away to show the interior of the casing and the dirt receptacle. Fig. 3 is a fragmentary view partly in plan and partly in section, showing the link connections for the bellows. Fig. 4 is a detail view, showing in section the tongue and parts immediately associated therewith for enabling the operator to hancue the device. Fig. 5 is a section, substantially on the line 55 of Fig. 6, looking in the direction of the arrow, and showing the valve mechanism. Fig. 6 is a vertical section, on the line 66 of Fig. 5, looking in the direction of the arrow, and showing the bellows mechanism with its valves.

A dirt receptacle is shown at 7,-and has generally the form of a fiat box. The nozzle appears at 8, and at 9 is a bail for detachably holding the nozzle upon the dirt receptacle. Mounted upon the nozzle 8 is a lug 9 which is engaged by the bail 9 in order to secure the nozzle upon the dirt receptacle. The bail 9 is journaled upon a pair of cars, one of which is shown at 10, and is adapted to swing upwardly, when disconnected by hand from the lug A dirt bag is shown at11, and islocated within the dirt receptacle 7 and in communication with the nozzle 8.

. Casters12, provided with having substantially the form of a keystone,

and being provided with gauze windows 15 for discharging air. Located centrally within the casing-'14 is a partition 16, this partition being provided with a slot 17 registering with an opening 17 in the bottom of the casing communicating with the dirt box or receiver, as may be understood more particularly from Figs. 2, 5 and 6. Mounted rigidly upon opposite sides of the partition 16 are bellows plates 18,19, the latter being provided with valve holes 20, 21. Extending over these holes are valves 22, 23. Two other bellows plates are shown at 24, 25. These two bellows plates are movable rela-' tively to the partition 16 and bellows plates 18 and 19, and are provided with valve holes 26, 27 and with valves 28, 29. Bellows webs are shown at 30, 31 and are connected with the bellows plates 18, 24, 19, 25.

caster wheels'13, ,are'mounted upon .a casing 14, the latter Mounted upon the bellows plates 24, 25

are brackets 32, 33,-which extend through slots 14 in the casing 14. Two links 34, 35 are pivotally connected with the brackets 33,

32. Aclevis 36 is mounted upon the partition 16 and is provided with a bolt 37. A.

tongue is shown at 38 and is provided with a slot 39 extending through it. A hand lever 41 extends through the slot 39, and is connected with the tongue 38 by a pivot bolt 42. The tongue 38 is provided with a metallie head 40, the latter having a slot 40 extending horizontally through it, and an opening for the bolt 27. The hand lever 41 is provided with a portion 43 extending through this slot. The links 34, 35 are pivotally connected to the portion 43 of the hand lever. The parts are so arranged that whenever the hand lever 41 is moved upon" the pivot bolt 42, relatively to the tongue 38, both of the bellows plates 24, 25 areshifted relatively tothe partition 16.

The various bellows plates and parts associated therewith together constitute two distinct bellows so arranged that a single movement of the hand lever 41 and tongue 38 relatively to each other will cause one of the bellows to be inflated and the other to be deflated. The tongue 38 is provided with a handle 44, and. the hand lever is provided with a handle 45, to facilitate the control of these parts by hand. Rivets 46, (see Fig. 4) secure the tongue 38'and the head 40 to gether. V v 7 The operation of my device is as follows: The parts being assembled and arranged as shown and described, the operator grasps the handles 4%, 45, and pushes or pulls the device along over the floor or other surface to be cleaned. The caster wheels 13' facilitate the handling of the device asa whole,

and enable the operator to bring the nozzle 8 quickly over any part which is to be operated upon by the cleaner. As the de vice is thus moved bodily around, or even while it remains stationary, the operator, by moving the handles 44 and 45 relatively to each other, operates the two bellows within the casing. Air, containing dirt removed from the article to be cleaned, is carried into the dirt receptacle 7, and the dirt is retained in the dirt bag 11. The air passes upwardly through the slot 17 and out through the various valve holes and makes its escape through the windows 15.

I do not limit myself to the precise construction shown, and variations may be made therein without departing from the spirit of my invention. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. In a vacuum cleaner, 'the combination of a receiver, a casing connected with said receiver and having substantially the form of a keystone, a portion of said casing being wider than said receiver, casters mounted upon the edges of the portion thus wider than said receiver, a tongue connected with said casing, bellows mounted within said casing, and means operable by hand for actuating said bellows.

2. In a vacuum cleaner, the combination of a receiver, a casing secured to said receiver, a tongue pivotally connected with 1 said casing, a hand lever pivotally connected with said tongue, bellows mechanism located within said casing, and links connected with said bellows mechanism and with said hand lever.

of a receiver, a casing connected therewith, a partition mounted within said casing and provided with a slot which communicates 3. In a vacuum cleaner, thecombination with said receiver, a plurality of bellows mounted within said casing, separate links connected with the different bellows, a single hand leverconnected with all of said links and adapted to swing relatively to said casing, and a tongue pivotally connected with said casing and adapted to swing relaside of said partition and communicating with said opening therein, separate links connected with the different bellows, a hand lever connected with all of saidlinks, a
